    "abstract": "The Poincare invariant coupled-channel formalism for two-particle systems\ninteracting via one-particle exchange, which has been developed and applied to\nvector mesons in Ref. [1] is applied to axial vector mesons. We thereby extend\nthe previous study of a dynamical treatment of the Goldstone-boson exchange by\ncomparison with the commonly used instantaneous approximation to the case of\norbital angular momentum l=1. Effects in the mass shifts show more variations\nthan for the vector-meson case. Results for the decay widths are sizable, but\ncomparison with sparse experimental data is inconclusive.",
